Hmmm. For the wheels and axles, you could use plastic drinking straws, and the plastic lids from cups that you get at fast food places. If you have some sort of a plastic box or bowl that has holes in the sides, you could put the straws through the holes, and thread the lids on so they would turn like wheels. You'd have to secure them with string, or something similar; maybe bread bag ties. I am not sure how you can get them to run off the rubber bands, but I am thinking of those balsa wood toy airplanes we all had as kids. Twist the bands, and as they unwind, they would have to turn the "axles" (straws) of the car.
Hope this helps some!
